问题 How many miners are trapped underground?
  
(21) A toxic mix of gasses inside a New Zealand coal mine kept rescue workers frustrated again Monday, as they waited for the go-ahead to try to reach 29 miners trapped underground. (22) No one has heard from the men—ages 17 to 62—since an explosion inside the mine around 4 p. m. Friday afternoon. Officials hope they are alive, though they do not know if the men found a safe place or whether parts or all of the mine collapsed. (23) To gather more information, rescue workers are planning to send a high-tech robot inside the mine, which is located on New Zealand’s west coast between Greymouth and Reefton.
    Police on Monday released for the first time the names, ages and nationalities of the 29 men. Most of the missing are from New Zealand, but there are also miners from Australia, Scotland and South Africa in the group.

选项 A、Most of them are young workers.
B、They don’t know each other well.
C、They are all citizens of New Zealand.
D、They have been trapped since Friday afternoon.
